REBOUND-CONTROLLER.

Application filed September 29. 1919.

To all whom it may Concern.

Be it known that LHAnnY G iminx binne, n. citizen of the United States,and a resii dent of Washington Court House, county of Fayette, :1ndState of Ohio, have made certain new and useful Improvements inRebound-Controllers, of which the following is e specification. 4

My invention is an improvement in re bound controllers, and has for itsobject to provide o. device ofl the character specified, adapted to bearranged between the frame of e vehicle and the axle, for controllingthe rebound to prevent shock und jar, wherein the arrangement is suchthat the device offers no impediment to the compression of the sprin butcushions the expansion, and wherein t e cushioning action may be voried.

In the drawings Figure 1 is a. side View showing the controller in use,

Fig. 2 is a vertical section through the controller,

Fig. 3 is a. section on the line 3--3 of Fig` 2.

he present embodiment of the invention is shown adj scent to the spring1 of a motor vehicle, the improvement being arranged between the axle 2and the frame 3 of the vehicle. The improvement comprises asubstantially U-shaped casing consisting of a body 4 and arms 5extending approximately at right angles to the body, and the body has nnextension 6 at one end, which is adapted to lap upon the axle 2 betweenthe axle and the spring, and to he secured in place by the clips whichconnect the spring to the axle.

A shaft 7 is journsled in openings in the firms 5 of the casing, andthis shaft hns keyed thereto n disk 8. The peril'iherul surface of thedisk is provided with recesses 10, four recesses being provided in thepresent instance, and each recess as shown consists of two portions. Oneof these portions of each recess luis one abrupt face and one inclinedface, and this portion of each recess receives rollers 11.

A housing encircles the disk, the housiiig consisting of zi ring shapedbody 12 hnving at one side edge a web lil which hns :in opening .forreceiving the shaft T. .it the other ed e, there is secured :i ring 14,by means o `screws as shown, and the web et one end and the ring at theother limit the Specification of Letters Patent.

tion of the disk moving to the rig t ot' Fig.

2, the rollers will move into the shallow portion of the recesses sindwill firmly grip the broke ring to the disk.

`To insure the proper engagement of the rollers, coil springs 15 arearranged in tubular housings 16 held in recesses extending substantiallycirculnferentially of the disk. These springs normally press Atherollers to werd the shallow portions of the recesses.

A brake bend 17 encircles the brake disk in spliced relation, the saidband being a split ring, the ends of which nre bent radially outward asindicated et 19 and nre connected by -a bolt and nut 20. The internalsurface of the ring is faced with a lining 21 of material havin a, higheo-eficient of friction. This liningr engages the broke disk when thebrnke isset.

A radial arm 22.is secured to one end of the shaft 7, and this arm isconnected by a link 23 with the frame 3 of the vehicle.. The arrangementis such that when the spring is compressed, that is, when the framemoves toward the axle, the disk S will be rotated with its upper portionmoving to the left of F ig. 2, and the rollers will not grip the brokering to the disk.

'lhe parts will slip idly past ench other, und the device will offer noresistance to the compression of the spring. When however, the springmoves away from the axis, that is. when the springs expend, the diskwill rotate in the opposite direction and will he gripped to the brakehousing 12mm-14. The rotation of the housing will be resisted by thebrake blind, and the :unount of resistance muy he nicely regulated h vnicnns of the nut and bolt '20, regulating' the pressure oi the hund onthe housing.

A rebound snuiihcr comprising n U-sluiped trame rigid with respect tothe axle of a vehicle, n shalt journnled transversely thrungl the z rmsof Suid frame and innig-.1 :1 ra-dml arm connected by u 11x11( wltlx the"fz-:mw of the:y vehicle, :x disk secured upon blxd Surroundng saidhousng and providd Wh m9111191 whereby its degree. of contrcin may berl-gnlateLL :L transverse pin extending; across the arms of the U-slmpedframe, um] :l VSh:lper.l bracket (carried by Said Emmi and.
